Is it permissible for my friend to sell a machine to a non-Muslim company if the company will pay the price of the machine to the bank through an interest-based (riba) method?

If the completion of the usurious loan transaction from the bank depends on selling your machine to the company, then it is not permissible to sell it to them; because that entails assisting them in usury, based on the words of Allah Almighty: "And do not cooperate in sin and aggression." And in the Hadith: "The Messenger of Allah (peace and blessings of Allah be upon him) cursed the one who consumes Riba, the one who feeds it, its scribe, and its two witnesses, and he said: they are equal." However, if the transaction between the factory and the bank regarding the loan has already been completed and does not depend on selling the machine, then there is no harm in that case, due to the absence of assistance in what is unlawful.
